Factors influencing reversion from virus infection in sweetpotato

Viruses limit sweetpotato ( Ipomoea batatas ) production worldwide. Many sweetpotato landraces in East Africa are, however, largely virus‐free. Moreover, some plants infected by the prevalent Sweet potato feathery mottle virus (SPFMV) may be able to revert to virus‐free status.
